A GYNANDROMORPH OF 
MELANOPLUS MEXICANUS MEXICANUS 
(SAUSSURE) EXTREME MIGRATORY PHASE 
(ORTHOPTERA: ACRIDIDAE ) * 1

The gynandromorph described in this paper was loaned 
the author by Dr. Roscoe E. Hill, Chairman of the De- 
partment of Entomology, University of Nebraska. The 
specimen was taken from the collections of the University 
of Nebraska State Museum and was returned to the Muse- 
um of that University. The specimen was collected at or 
near Pine Ridge, Nebraska, in July. No further definite 
data regarding the origin of the specimen was available 
such as year when the specimen was collected or the name 
of the collector. For purposes of comparison the author 
of this paper borrowed from the Nebraska State Museum 
through Dr. Hill a normal male and a normal female speci- 
men of Melanoplus mexicanus mexicanus (Saussure) 
Extreme Migratory Phase. These specimens were collected 
at or near West Point, Nebraska. Neither of these speci- 
mens had a date label attached to them but one of the 
specimens had a label attached to it with the following 
data printed in ink, by hand: Melanoplus spretus Thos. 
(Det. L. Bruner). 
Since the gynandromorph and the borrowed male and 
female grasshoppers were apparently old, it is reasonable 
to believe that Professor L. Bruner might have been the 
collector not only of the normal grasshopper but of the
